✦ Synopsis
Underwater observations of the three common fish species Alburnus alburnus (1,. , 1758), Rutilus rutilus (J,., 1758) and Scardinius erythrophthalmus (JA., 1758) in a small part of thc Danube flood area near Vienna have been made from June t o October 1985 and 1986. Particular emphasis has been laid on the partitioning of feeding resources and habitat. It has been established that these species prefer different water zones. Alburnus a. and Scardinius e . are "obligate" schoolers (BREDER, 1967) whereas Rutilus r. is a facultative schooler. While feeding liutilus r. and Scardinius e. form "aggregations" (BREDER, 1959) and both adopt equivalent feeding techniques. Furthermore Alburnus a. is a quick moving species living near the surface and chasing mostly in schools. While inter-and intraspecific aggression is rarely observed for Rutilus r. and Scardinius e . , Alburnus a. often show interspecific actions.
